DEFINITION OF CLOCK AND CYCLE
q Operation source clock
The operation source clock is the source clock to operate this
product. In this product, the following clocks are used.
Clock (f(XIN)) by the external ceramic resonator
Clock (f(XIN)) by the external RC oscillation
Clock (f(XIN)) by the external input
Clock (f(RING)) of the on-chip oscillator which is the internal
oscillator
Clock (f(XIN)) by the external quartz-crystal oscillation
Register MR
System clock
f(STCK) = f(XIN)
f(STCK) = f(RING)
f(STCK) = f(XIN)/2
f(STCK) = f(RING)/2
f(STCK) = f(XIN)/4
f(STCK) = f(RING)/4
f(STCK) = f(XIN)/8
f(STCK) = f(RING)/8
Table Selection of system clock
: 0 or 1
Note: The f(RING)/8 is selected after system is released from reset.
When on-chip oscillator clock is selected for main clock, set
the on-chip oscillator to be operating state.

q System clock (STCK)
The system clock is the basic clock for controlling this product.
The system clock is selected by the clock control register MR
shown as the table below.
q Instruction clock (INSTCK)
The instruction clock is the basic clock for controlling CPU. The
instruction clock (INSTCK) is a signal derived by dividing the
system clock (STCK) by 3. The one instruction clock cycle gen-
erates the one machine cycle.
q Machine cycle
The machine cycle is the standard cycle required to execute the
instruction.

Notes 1: Pins except above have just single function.
2: The input/output of P30 and P31 can be used even when INT0 and INT1 are selected.
3: The input of ports P20–P22 can be used even when SIN, SOUT and SCK are selected.
4: The input/output of D6 can be used even when CNTR0 (input) is selected.
5: The input of D6 can be used even when CNTR0 (output) is selected.
6: The input/output of D7 can be used even when CNTR1 (input) is selected.
7: The input of D7 can be used even when CNTR1 (output) is selected.
